After upgrade to alsa-lib-1.0.10-1 the dmixer-plugin does no longer work. With alsa-lib-1.0.9-2 everything works fine.
I attached my /etc/asound.conf. It's the regular one from the wiki-article "Allow multiple programs to play sound at once".

This is the output of alsaplayer:

ALSA lib pcm_dmix.c:819:(snd_pcm_dmix_open) unable to open slave
snd_pcm_open: Das Gerät oder die Ressource ist belegt (default)
Failed to initialize plugin!
Failed to register plugin: /usr/lib/alsaplayer/output/libalsa_out.so
Failed to load output plugin "alsa". Trying defaults.

NOTE: THIS IS THE NULL PLUGIN. YOU WILL NOT HEAR SOUND!!

have You tried it without that config file?
the latest releases should "dmix" automatically - maybe not optimally in all cases, but Your config file is really quite generic.

Yes, i've already tried this without success. :-(

What version is Your alsa-lib and -drivers (kernel)?
Comment by Thomas Karmann (samoht) - Friday, 09 December 2005, 16:18 GMT
kernel version: vanilla 2.6.14.3
alsa-lib: as said, 1.0.9-2 is working, 1.0.10-1 is not working.
Soundmodule is snd_ice1712.

Do you know how I can permanently downgrade a package? I put "alsa-lib" in the "HoldPkg"-Line in /etc/pacman.conf, but "pacman -Syu" still tries to upgrade it.
Comment by Matiss Piesins (piesis) - Friday, 09 December 2005, 18:54 GMT
Hmm - can you get any sound at all?
that alsaplayer output indicates that the soundsystem isn't accessible at all, oder ist schon belegt.

whats the output of
$ cat /proc/asound/card0/pcm0p/info
(the default output pcm's "p"-playback channel)


You need IgnorePkg, not HoldPkg (just read it in man pacman :)

HoldPkg = <package> [package] ...
If a user tries to --remove a package that's listed in HoldPkg, pacman will ask for confirmation before proceeding.
IgnorePkg = <package> [package] ...
Instructs pacman to ignore any upgrades for this package when performing a --sysupgrade.

Hi.

I just wanted to let you know that I encountered the same misbehaviour of the current alsa.
Alsa version 1.0.9 was working fine with me, version 1.0.10 does not.
Dmixer refuses to work regardless of using a asound.conf or not.
I even use the same sound card module(ice_1712).

Does the sound work with other distros/livecd's?
There aren't many liveCDs with alsa 1.0.10, but at least the newest BerryLinux and 64 Studio claim to have it (see distrowatch.com).

IMHO, bugtrack.alsa-project.org could be more helpful in this case.

If I do "mpg123 *.mp3" following error appears, so it seems, that even the normal pcm out doesn't work:
ALSA lib pcm_direct.c:812:(snd_pcm_direct_initialize_slave) requested or auto-format is not available


Here's content of /proc/asound/card0/pcm0p/info:
card: 0
device: 0
subdevice: 0
stream: PLAYBACK
id: ICE1712 multi
name: ICE1712 multi
subname: subdevice #0
class: 0
subclass: 0
subdevices_count: 1
subdevices_avail: 1

Thanks

I got the same output for /proc/asound/card0/pcm0p/info.
PCM output works for me without problems. Only simutanously playing of audio streams does not work.

Adding "format S32_LE" to the dmixer-section of asoundrc seems to fix the problem here.
Read https://bugtrack.alsa-project.org/alsa-bug/view.php?id=1659 for more information.

thanks, samoht, for the comment, but, could u perhaps duplicate the information in that link elsewhere, and link to that instead? or copy out that info here?

Cos... (and here comes my rant)

does the alsa-project bug viewer SUCK, man!!!

first, this is a https link - what for??? And then u burden me with a useless cert that isnt even properly certifiable (so i have to click, and ignore that warning). What for is my question. Is the information soo valuable that u can't use http??

Never mind. Second, after this horrible atrocity, **u have to login**, before u will be able to see the bug info. How nice.

</End Rant>

Sorry, but I've nothing to do with alsas bug-management. The essential information is already in my last post.
The bug is removed in current cvs of alsa-lib.

BTW: you can visit the link by clicking on "[ Guest login (view only) is also available. ]".

> Sorry, but I've nothing to do with alsas bug-management.

yes, of course, i know. Sorry about that. The "u" in my rant was a generic "u".

> BTW: you can visit the link by clicking on "[ Guest login (view only) is also available. ]".

oh, sorry about that. Missed that. Thanks.
